I have a tree with a dataprovider that is an XMLListCollection. The source of the dataprovider is the result of a HTTPService:
Code:
<s:HTTPService id="xmlService" showBusyCursor="true" result="handlexmlResult(event)" resultFormat="e4x" fault="xmlService_faultHandler(event)"/>
[code]....
i have the following code:
<mx:Repeater id="user" dataProvider="{data}">
<mx:VBox styleName="repeaterVBox">
<mx:Text text="{user.currentItem.a}. {user.currentItem.b}"
[Code]....
the dataProvider 'data' updated itself every 3 seconds, so every 3 seconds that is a flicker of some sort, i see for a really short time an empty area and then it gets redrawn again. is there a way to make the update somewhat faster ?
In a DataGrid, how can I force data() of all itemRenderers on visible rows to be called when I've made an update to the dataProvider.I'n the following the Grid isn't updated after pressing doSomething. If I have a large list the update is done when scrolling down and then back up again, or in the case of the TreeGrid i open/close a node.
<?xml version="1.0" ?>
<mx:VBox
xmlns:mx="http://www.adobe.com/2006/mxml"[code].....
Is there a way so that every time the list is changed (data add, data deleted, etc.), the list will re-update or "refresh?"
View 2 RepliesI have a simple list and a background refresh protocol.When the list is scrolled down, the refresh scrolls it back to the top. I want to stop this.I have tried catching the COLLECTION_CHANGE event and validateNow(); // try to get the component to reset to the new datalist.ensureIndexIsVisible(previousIndex); // actually, I search for the previous data id in the IList, but that's not importantThis fails because the list resets itself after the change).I hate to use a Timer, ENTER_FRAME, or callLater(), but I cannot seem to figure out a way.The only other alternatives I can see is sub-classing the List so it can catch the dataProviderChanged event the DataGroup in the skin is throwing.

I'm trying to update a List component pushing new items inside his DataProvider object.
I've tried with a:

but the list doesn't change, anyone has some suggestions?

What is the role of source for an ArrayCollection or XMLListCollection? Is it used just once - when constructing a new ArrayCollection or XMLListCollection object and is it copied to some internal data structure of that object?
Because nothing is updated when the source Array (or XMLList) is being modified and the documentation confirms it too: The underlying XMLList for this collection. The XMLListCollection object does not represent any changes that you make directly to the source XMLList object. Always use the XMLListCollection methods to modify the collection.
This property can be used as the source for data binding. When this property is modified, it dispatches the listChanged event.
I'm asking because Flex examples related to dataProviders always use some Array or XMLList as source of data for a data-driven component. And I wonder, if using Array or XMLList is necessary at all - when for example loading data from external PHP-script.
When the XMLListCollection is updated in the DataGrid, I want it to add the XML (bind it) into the Model. How would I do this? Or if not possible, how would I manually add XML into the Model?
This is a rough example of what I'm trying to do. Adding data to the DataGrid works fine; it just doesn't go into the Model when sending to the HTTPService.
<mx:Model id="model">
<root><colors>{collection}</colors></root>
</mx:Model>
<mx:XMLListCollection id="collection" />

I have an XmlListCollection() with 73 columns and multiple rows. Is there a way to convert this to an Array()? I'm trying to access the "data" object sent through an rendererProvider and it appears comes across as null if it's not in an Array().
View 0 RepliesI am deploying Updates via SCUP and SCCM to hundreds of Computers. Fortunately Adobe provides an SCCM Update Catalog for both Adobe Flash ActiveX and Adobe Flash Plugin. But now my Problem: After publishing the Update via SCCM, the client is not supposed to be interfered with the Update Progress (which is working) I figured the Updater works like this: First SCCM checks if a Update needs to be deployed, if this is the case, The Flash Updater begins. First the old Flash Version is beeing uninstalled. But now: if the Client has a Browser Window (IE, or Firefox) open, the Updater is not able to install the new Flash Version and quits with an Error. This leaves the Client PC without any Flash (because its being uninstalled before) How can I prevent Flash being uninstalled due to the Update progress not working while a Browser window is open?
View 1 RepliesI am trying to display content of xmllistcollection in different fields in my datagrid however unless I use an itemrenderer the value is not displaying in the grid. The xmllistcollection is populated from a webservice call. Inside my item renderer i use a custom namesspace to retrieve contents from the xmllistcollection
value.ns::firstName
However if I try something like
dataField = "ns::firstName"
In the datagrid without using an item renderer I get no data output.

Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?

How do I set the dataprovider in actionscript? I have:

adg1.dataProvider = pagedResult.lastResult;

Normally in Flex you use a collection like ArrayCollection as the dataprovider for components. I often have data stored as a dictionary whose values I would like to use as a dataprovider.
